OpenRISC 1000

A good idea, suggested on the OpenRISC mailing list by Originally noted by Shinji Wakatsuki swaka@hdlab.co.jp

By defaut, or1ksim_init needs image_file essentially.

int or1ksim_init ( const char config_file, const char image_file, ... )

I hope or1ksim_init is allowed a following configuration. Current or1ksim occurs segmentation fault.

int or1ksim_init ( simple.cfg, NULL, ... )

In this case, or1ksim does not load image_file, just setup internal state.

I asuume a following environment. Or1kSim - TLM2.0Bus - Flash (Boot Rom) - RAM - HARDWARE Engine

Flash is responsible for loading image_file. Using above environment, image file load sequence deos not occur. Use can analysis real bus performance.

This behavior is in Or1ksim 0.3.0rc3. Note that if you don't specify a debug connection, then you will have no mechanism to load a program!
